Roof Extensions and Overhangs

Extensions can improve the appearance of a building but will cost more. Roof extensions add "curb-appeal" to some buildings, but will take more time to complete the erection of the building because of the amount of extra covering trim. Extensions can also help a building merge in better in an environment of conventionally constructed buildings in commercial areas. An overhang offers you some protection from the rain and shade from the sun. These options can be important when you receive many visitors to your building, by offering shelter from the elements.

We offer two types of roof extensions: (1) Gable Extensions for endwalls (2) Eave Extensions for sidewalls. Using our system, you can easily and quickly design and price buildings with overhangs up to 5' on any or all of the walls. When in the Building Accessories section select Roof Extensions.

Frame Types

Unlike any of our competitors, we allow you to price all building frame types. Select from Clear-span or Modular rigid-frame buildings. We allow you the full flexibility to choose Gable, Single Sloped or Offset Peak building shape. By far, we offer the widest selection of building and frame types. For options not available through the online system, you will need to request a special quote.

Clear-span Frames - A clear-span rigid frame offers strength and economy. Since no interior supports are necessary, this design is best when you require large areas of clear and uninterrupted space. Factories, warehouses and agricultural buildings are just a few building types that may utilize a clear-span frame building. A clear-span design does have size limitations. As the desired width increases, the frames will become larger and heavier to carry greater loads across the length of the frame. At some point the cost will outweigh the benefit. Even so, clear-span buildings are still effective for buildings as wide as 150' feet and wider in some cases.

Modular Frames - Modular frames use interior columns to evenly distribute the load; reducing the cost of both the frame and foundation of extra wide buildings. The economical advantages become obvious when a building width is about 100' wide or wider. As a result, almost all buildings 100' wide or wider have interior support columns. Modular designs are often used for large factories and warehouses.

Single Slope Frames - Single slope frames have high and low eave heights creating a roof that "slopes" from side to side. To select a single slope design, you specify one eave height and define the roof pitch. Single slope designs are frequently used for strip shopping centers, offices, and RV/Boat storage facilities.

Just about every steel building has at least one framed opening. It is not unusual for buildings to have several openings. Most openings are created for an overhead door, but can be used for the installation of glass fronts or other entries. Most other online sellers offer "field located" framed openings, which require cutting and fabricating on the job site. Metal Building Depot always provides factory-located openings unless your project requires something otherwise.

Metal Frame

What is a stronger material than metal? Metal frame buildings are nearly indestructible. You can certainly feel safe in even the worst weather in a metal frame structure.

Erecting a metal frame pre engineered building might sound like a difficult project, but despite this perception, it is really not the case. Metal frame structures are cut to precise measurements and a complete set of building plans will aid in the assembly process.

If you need help constructing your metal building, you will incur additional expenses, so be sure to factor construction cost into your budget when purchasing a steel building.

Advantages of Metal Buildings

LOW COST - Our steel buildings are more economical than conventional methods due to the originating costs and reduced labor. Complete steel buildings are delivered to the jobsite and quickly erected. QUICK CONSTRUCTION - On average, a steel building system can be completed in approximately two-thirds the time required for conventional construction. BETTER APPEARANCE - The appearance of steel buildings can easily be enhanced with stucco, stone, brick or glass. Metal building systems can attain a remarkable exterior that will merge with the ambiance of the building's surroundings. LOW ENERGY CONSUMPTION - A suitably insulated metal building can drastically decrease heating and cooling expenses. Insulated roof and wall systems preserve and reassure thermal efficiencies. LOW MAINTENANCE - Extended life materials reduce maintenance, and eliminate troubles such as structural deterioration, rotting and insect damage. EXPANDIBILTY - It is easy to enlarge a building by removing the end walls, erecting new framework and adding matching wall and roof panels. In most situations, the original end wall panels can be reused.

Facings as Vapor Barriers

The main function of facings is to act as a vapor barrier. While a vapor barrier may not necessarily be able to stop the flow of water vapor, it does an excellent job of minimizing the rate and volume of the flow. This prevents moisture from accumulating within the insulation blanket and the structure, which translates into consistent thermal values and lower heating and cooling costs.

Facings intended to serve as vapor barriers should be installed on the inner, heated surface of the insulation, where vapor pressure is the highest. This helps in preventing vapor from reaching the cooler air and condensing.

VAPOR BARRIERS PREVENT VAPOR FROM REACHING COOLER AIR AND CONDENSING.
